第五讲内因火灾的发生原因内因火灾一般发生在煤矿和硫化矿山。据统计,我国目前已经开采的矿山,约有40％的煤矿、20～30％的硫铁矿、5～10％的有色金属或多金属硫化矿具有内因火灾危险。如大同矿务局煤峪口矿、阳泉矿务局、开滦矿务局赵各庄矿、铜陵有色金属公司铜官山矿、德保硫铁矿、大厂矿务局铜坑锡矿等都是典型的内因火灾矿山。内因火灾能使大量的有用矿物资源遭受损失,恶化矿井劳动条件,有时还会造成人身伤亡事故。
Lecture 5 Causes of Internal Fires Internal causes of fire generally occur in coal mines and sulfide mines. According to statistics, about 40% of mines, 20-30% of pyrite and 5-10% of non-ferrous or polymetallic sulphide mines that are currently mined in our country are endangering fires. Such as Datong Mining Bureau Meiyukou mine, Yangquan Mining Bureau, Kailuan Mining Zhaozhuang Coal Mine, Tongling Nonferrous Metals Company Tongguan Hill, Debao pyrites, Dachang Mining Bureau Tongkeng Tin and so on Is a typical internal fire mine. Internal causes of fire can make a lot of useful mineral resources suffered losses, deterioration of working conditions in mines, and sometimes cause personal injury.
